A conceptual model is the perception a person has about a product or service. The conceptual model can change or be reinforced over time and is determined by the contact a person has with the product. Conceptual modeling can be carried out at a very early point in the design cycle so that there is a basic understanding of how users conceive tasks and this can then be brought to bear on final design. The ability to sketch conceptual models quickly and easily can save large amounts of time in functional design and help deliver more intuitive applications. Shifting from the 3D digital world to a physical part will accelerate your product development process and lower cost. A 3D printed part is more effective at communicating the design, so you can make better decisions faster.
